* Don't collect exception stack if it won't be logged

* Bump version

* Fix tests for new version of `ConcurrentUtilities`

`ConcurrentUtilities` changed an (internal) fieldname of the `Pool` type

* Remove invalidation CI check

This has been failing for quite some time with some internal error. Also

when it errors (xref
#920 (comment)).
